It wasn't long ago that we heard about the "lock-up" woes D4 and D800 owners were experiencing on their shiny new shooters, but luckily for them, Nikon just outed a fix to take care of those issues. Aside from solving the aforementioned annoyance, the firmware update (B:1.01) also mends a problem allowing RAW files to be network-transferred while in JPEG-only mode, as well as a bug causing bits like aperture and exposure compensation to change unexpectedly when using certain custom settings. You can grab the updates now via the source links below, and be sure to let us know how it all turned out in the end.
